History:
BTS - Gladiatrix, like the majority of the members of the UCWF,
presumably obtained her powers by undergoing the strength
augmentation process of Power Broker INC. She became a member of
the Grapplers after the group affiliated with the UCWF and
greatly expanded its membership.

(Thing I#33) - Gladiatrix was one of the Grapplers
who were forced to restrain the original Titania after she lost
her title to Battleaxe. Shortly thereafter, Titania was killed by
the assassin Scourge, posing as a Grappler named Golddigger.
Battleaxe believed (incorrectly) Scourge to be a single person, a
man, and was frustrated because she couldn't take out her anger
on Scourge, so she sought the closest male target.
Scourge/Golddigger (while making her getaway) told the other
Grapplers that Titania had been shot by a man, and Battleaxe
allowed them to believe it was the Thing. Gladiatrix and the rest
dogpiled on top of the Thing until Battleaxe finally admitted
that she was with the Thing, and that he couldn't be the killer.

(Captain America I#352) - Gladiatrix, alongside
Blue Shield, the Mechanaut, and Speedball, tried out for the
Avengers, under the supervision of Captain America. Cap was
called away to deal with the Soviet Super Soldiers, who had
arrived on Avengers Island seeking amnesty. Still believing this
to be part of their test, Gladiatrix and the others attacked the
Soviets (and were taking a beating). Gladiatrix was just about to
get mauled by Ursa Major, when Cap arrived and broke things up.

(Captain America I#387-388-BTS, 389-391, #392 - BTS) - Gladiatrix
answered an invitation to join Superia's Femizons. She traveled
aboard the luxury liner, the S. S. Superia, to Femizonia Island.
En route, Captain America and the Paladin were caught attempting
to ascertain their activities (that would be spying
on them). Gladiatrix, along with an army of
super-villainesses attacked and captured the two.

(Captain America I#411-414) - Gladiatrix was present at the AIM
Weapon Expo on Boca Caliente. She was part of an even bigger army
of costumed criminals who attempted (and failed) to subdue
Captain America when he was exposed in their midst.

(Civil War: Front Line#4) - Gladiatrix met with other unregistered heroes at a secret hideout in Manhattan. During an attack of Iron Man, his Pro-Registration heroes and S.H.I.E.L.D. agents she was told by Battlestar to bring Sally Floyd, a reporter, to the east passage. Sally Floyd got away, but an explosion buried Gladiatrix beneath debris and she was arrested.

(Amazing Spider-Man I#535) - When Iron Man and Spider-Man visited the prison, Gladiatrix was seen in a cell. She was ensconced within a virtual reality simulator to keep her subdued.
